I've always like mech tach drives and since I have the one, for my 361 industrial block, I've decided to use it, with a Smiths tach.
Has anyone used one in their eng?
It's has a single point cam and I will use a PerTronix conversion but, if there are better ones, please tell me about them. I've heard there can be issues with the PerTronix, I'd like to hear about those, also.
The 391/industrial dist, is about a inch taller than a std dist, that's because part of the governor is below the breaker plate and pulls vacuum through the shaft, to operate a spring loaded weight. It also allows me to use the 5/16 drive and oil pump.
I took it apart today, removed the governor assy and it's soaking, to clean it up. It doesn't look any different than a std points dist, from the weights up.
